A vSphere administrator needs to add redundancy to an ESXi 5.x management network on a vSphere Standard Switch.
Which method should the administrator use to create redundant management networks?
A. Configure the management network vSwitch with two active uplinks
B. Configure an additional management portgroup on the same vSwitch
C. Create a second management network on a second vSwitch in the same subnet
D. Create a second management network on the same vSwitch in the same subnet
Correct Answer: A
Explanation/Reference:
Explanation:
NIC teaming combines multiple network connections to increase throughput and provide redundancy should a link fail. To create a team, you associate multiple physical adapters to a single vSphere standard switch.
Incorrect Answers:
B: This option is part of a VLAN configuration, but won’t provide redundancy.
C: Creating a second management network on a second vSwitch in the same subnet provides Network path redundancy between cluster nodes, which is important for vSphere HA reliability. The scenario does not imply that the switch is in a cluster configuration.
D: A second management network cannot be created on the same switch.
